Definitions

  • the invention generally relates to a push-type key actuator for a lock assembly which can be used to manually actuate an override mechanism to enable bolt retraction.
  • the invention also relates to lock assemblies and/or escutcheons including such an actuator.
  • the locking member may be motor driven to engage with the actuation mechanism of the bolt, with the bolt itself to lock the bolt in the extended state, or with the lever clutch mechanism.
  • the electric motor On detection of correctly coded user credentials the electric motor operates to move the locking member to permit user retraction of the bolt.
  • a user inserts a key into the rotational key cylinder and rotates the key, which in turn rotates the rotational key cylinder from its rest position to its actuated position.
  • the rotational motion of the rotational key cylinder is converted to a linear motion to slidably engage the locking member with the lever clutch mechanism.
  • the user can then retract the bolt by operating the lever whilst the rotational key cylinder is held in the actuated position. Rotating the key back to its rest position and removing the key, causes the locking member to disengage from the lever clutch mechanism (and thus disengage the lever clutch mechanism).
  • rotational key cylinders are typically mounted into the front face of an escutcheon, such that the longitudinal axis of the rotational key cylinder is parallel with the axis of rotation of a door lever.
  • the escutcheon then has a large profile from the door to accommodate the length of the rotational key cylinder, or the cylinder protrudes from the escutcheon
  • the rotational key cylinder is visually noticeable on an electronic lock.
  • the key cylinder is a backup credential for electronic locks, i.e. only used when power or electronic failure and so the preference is often to visually conceal the cylinder on electronic locks.
  • the rotational key cylinder also has a housing around the cylinder which typically has a diameter of at least 16 mm.
  • a rotational pin style cylinder requires the escutcheon to be 17.5 mm thick at a minimum, and of greater thickness if the escutcheon includes a back plate.
  • the escutcheon needs to be sufficiently thick to provide sufficient clearance for a user to insert and turn the key.
  • An escutcheon of 17.5 mm thickness with the rotational key cylinder mounted in a side or base thereof makes it difficult for a user to insert and turn a key to actuate the override, due to the proximity of the door face making it very difficult for the user to operate via rotation of a key since there is minimal clearance between a user’s fingers and the door face when a user attempts to rotate the key.
  • Some designs that use a rotatable pin cylinder on the bottom/side of escutcheon incorporate the keyhole in the barrel so that it is on an angle to the door face - i.e. key insertion is not parallel to the door face. This is done to help to overcome the key head contacting the door face when the key is rotated.
  • the disadvantage of this design is that key insertion is not- intuitive, and it is difficult to align the key into the keyhole especially as the user cannot easily see the cylinder. In such cases, the user may need to bend down to see the keyhole, and even then, it is still difficult to see.
  • the linear push force overcomes the spring bias of the motor driven locking member to move the motor driven locking member out of the lock position.
  • the detent arrangement comprises a notch on the push-type key actuator and a spring-loaded ball within the escutcheon, the notch and spring-loaded ball configured to engage when the push-type key actuator is in the engaged position.
  • the lock assembly further comprises a spring configured to oppose a key insertion force and substantially hold the key driven slide in the rest position during key insertion.
  • the body of the key driven slide has a crosssection in a plane orthogonal to the longitudinal axis, the cross-section having a short axis and a long axis perpendicular to one another, the short axis being substantially parallel with the rotation axis.
  • the lock assembly further comprises a detent arrangement configured to hold the key driven slide in the engaged position.
  • the engagement member comprises a first portion mounted to the key driven slide and a second portion mounted to the first portion, the first portion and the second portion being movable relative to one another in a direction along the axis between a contracted state and an elongated state.
  • the second portion is spring biased from the first portion such that the engagement member is in the elongated state.
  • the first portion is a shaft and the second portion is a sheath, the sheath being slidably and coaxially mounted to the shaft.
  • the engagement member projects out of the escutcheon via an opening in the rear face and into engagement with the manual override mechanism.
  • the engagement member is an engagement pin.
  • an escutcheon having a front face and a rear face, and one or more lateral walls extending from the front face to the rear face, the escutcheon comprising: a hand operable member mounted to the front face that is user actuatable about a rotation axis from a rest position to an actuated position; and a push-type key actuator mounted within the escutcheon with a keyhole accessible from a lateral wall of the one or more lateral walls, the push-type key actuator actuatable to provide a linear push force along a longitudinal axis thereof on insertion of a correctly coded key therein to actuate an override mechanism of a bolt locking mechanism; wherein the longitudinal axis is substantially orthogonal to the rotation axis.
  • the bolt locking mechanism is housed within the escutcheon.
  • the push-type key actuator comprises an engagement pin for engaging the override mechanism, the engagement pin projecting through an opening in the rear face.
  • the push-type key actuator is according to the second aspect of the invention, and/or embodiments, and/or forms thereof.

  • the push-type key actuator is configured to engage with a lock override mechanism, which may be arranged either within the escutcheon itself or be contained within a lock cartridge, such as a mortice style lock.
  • the lock override mechanism is a manually actuatable mechanism which is operable via the push-type key actuator to disengage a motor driven locking mechanism which stops the lever from being able to retract the bolt, for example by locking the bolt in the extended position or by disengaging the lever from the bolt such that the lever is not actuatable to retract the bolt.

  • Door frame 102 also includes first and second lateral openings 120A and 120B which pass from an exterior facing side through to the interior facing side thereof to allow installation of exterior escutcheon 104 and interior escutcheon 108 in an operatively connected manner.
  • levers 106 and 110 are operatively connected with each other and with lock cartridge 112 via a spindle 116 which passes through cavity 120A. In this way, when lock cartridge 112 is in a passage mode, either of levers 106 and 110 may be actuated, such as by a user applying a downward force to rotate handles 106 and 110, to turn spindle 116 and retract bolt 114.

  • Both exterior escutcheon 104 and interior escutcheon 108 can include a push-type key actuator to the manual override mechanism. The operation of the push-type key actuator and the manual override will be discussed in more detail below.
  • Figure 2 is a perspective view illustrating lock system 100 installed on door frame 102 with retractable bolt 114 in the extended state, such as when the door with lock system 100 installed thereon is in a closed position.
  • Figure 3 is a plan view of the underside of escutcheon 108 showing a keyhole on an external face of push-type key actuator 300 mounted in the base thereof.
  • Lock cartridge 112 comprises a cartridge housing formed from a cartridge body 400 and cover plate 402 which are affixed together via screws.
  • the cartridge housing contains retractable bolt 114, spindle cam 406, an actuator in the form of slide 408 and driven arm 409, auxiliary bolt 410, a latch locking mechanism in the form of a pivot locking arm 412, and torsion springs 414 and 416.
  • the cartridge housing also contains a motor module 418 having a motor, an electronic door position sensor 420 in communication with motor module 418, a motor driven locking member in the form of a locking slide 422, and a manually actuated lock slide override arm 424.
  • Retractable bolt 114 is rotatable about a central mount 404 between an extended position in which an end portion in the form of hook 426 extends outside the cartridge housing to engage with a recess on a strike plate or the like (not shown) and a retracted position in which retractable bolt 114 is substantially housed within the cartridge housing.
  • Retractable bolt 114 is spring biased via torsion spring 414 into the extended position.
  • retractable bolt 114 can be retracted by a user on rotation of handles 106 and 110 which are engaged with spindle cam 406 via spindle 116.
  • Spindle 116 is engaged in fixed relation with spindle cam 406 via a spindle passage 427 such that actuation of handles 106 and 110 from their rest position also rotates spindle cam 406 via spindle 116.
  • actuation of handles 106 or 110 causes rotation of spindle cam 406 in a direction such that spindle cam 406 rotates toward the first side of lock cartridge 112.
  • Spindle cam 406 includes arm 428 with a drive tab 429.
  • Drive tab 429 is seated within upper portion of slot 430 of slide 408 such that on rotation of spindle cam 406 drive tab 429 slides within slot 430 from the upper portion thereof into the lower portion thereof. This in turn causes slide 408 to move longitudinally from its rest position to an actuated position in a direction toward retractable bolt 114.
  • Rotation of spindle cam 406, causes surface 406A of spindle cam 406 to contact surface 409A of driven arm 409. This causes driven arm 409 to rotate toward the first side of lock cartridge 112. Driven arm 409 is engaged with retractable bolt 114 via a boss 409B which engages within a slot of retractable bolt 114. This causes retractable bolt 114 to be moved from the extended position into the retracted position, such that hook portion 426 is substantially withdrawn within the cartridge housing.
  • lock cartridge 112 The operation of lock cartridge 112 will be described below with reference to Figures 6 to 12.
  • auxiliary bolt 410 In the door closed position, auxiliary bolt 410 is in the depressed position in which pivot locking arm 412 is pushed by auxiliary bolt 410 to a position where it is disengaged from retractable bolt 114.
  • Door position sensor 420 is arranged to detect the position of locking arm 412 and communicate this with motor module 418 or communicate to user via app or similar.
  • Another advantage is that by running the wiring along the second side of lock cartridge 112, this allows for wire routing without taking up valuable space within the housing of lock cartridge 112 or without having to increase the size of the housing (such as depth, length, or thickness) to accommodate that wiring. Increasing the size of the housing of lock cartridge 112 would mean that the lock cartridge 112 could not be fitted to doors having small/narrow frames.
  • Figure 7 is an internal view of lock cartridge 112 showing the arrangement of components when a user actuates spindle cam 406 via handles 106 or 110 from the unlocked operating state of Figure 6 to retract retractable bolt 114 in a door open position.
  • spindle cam 406 is rotated over its full range of motion from its rest position to its actuated position.
  • the rotational motion of spindle cam 406 causes drive shoulder 406A to act on surface 409A of driven arm 409 to rotationally move driven arm 409 toward the first side of lock cartridge 112. Movement of driven arm 409 then causes retraction of bolt 114 via engagement between boss 409B on driven arm with slot 114A in bolt 114.
  • auxiliary bolt 410 On opening the door, auxiliary bolt 410 is sprung outward under spring bias provided by torsion spring 416 which causes pivot locking arm 412 to drop into engagement with upper surface of retractable bolt 114.
  • Door position sensor 420 detects the presence of pivot locking arm 412 in the engaged position and communicates this to motor module 418 and/or to a user via app or similar.
  • Figure 8 is an internal view of lock cartridge 112 showing the arrangement of components after a user has released handles 106 or 110 after actuating lock cartridge 112 to open the door as shown in Figure 17 and handles 106 or 110 return to the neutral position.
  • auxiliary bolt 410 On closure of the door, auxiliary bolt 410 comes into contact with a strike plate or the like on an opposing door frame which causes auxiliary bolt 410 to be pressed inward. The inward movement of auxiliary bolt 410 lifts pivot locking arm 412 away from retractable bolt 114. Retractable bolt 114 is then sprung to the extended position under spring bias of torsion spring 414. Pivot locking arm 412 is moved from door position sensor 420 which relays to motor module 418 or electronics that the lock is in a door close state as generally illustrated in Figure 6. Motor module 418 is retained in the unlocked state.
  • locking slide 422 does not prevent retractable bolt 114 from being moved from the extended position to the retracted position.
  • locking slide 422 prevents retractable bolt 114 from being moved from the extended position to the retracted position.
  • locking slide 422 includes tip 423 which is received in a complementary recess in retractable bolt 114 which provides a physical barrier to movement of retractable bolt 114 from the extended position to the retracted position.
  • FIG 10 is an internal view of lock cartridge 112 with motor slide 602 in the active position and retractable bolt 114 in the extended position, with bolt 114 locked by locking slide 422.
  • spindle cam 406 can be partially rotated which permits some movement of retractable bolt 114 toward the retracted state.
  • the engagement between locking slide 422 and retractable bolt 114 prevents linear movement of slide 408 which delimits movement of spindle cam 406.
  • spindle cam 406 comprises drive tab 429 which is located within slot 430 of slide 408. On rotation of spindle cam 406, drive tab 429 is moveable within slot 430 which causes slide 408 to linearly move its rest position to its actuated position.
  • slot 430 has a first portion 430A and a second portion 430B. Movement of drive tab 429 within first portion 430A of slot 430 does not cause linear movement of slide 408. Linear movement of slide 408 is caused by movement of drive tab 429 within second portion 430B of slot 430.
  • partial rotation of spindle cam 406 is possible (e.g., by a user actuating a lever to take up clearances between bolt notch 500 (see Figure 5) and tip 423 of locking slide 422) which results in drive tab 429 moving within first portion 430A of slot 430. This movement results in partial retraction of retractable bolt 114.
  • Actuation of the push-type key actuator causes lateral movement of override pin 122 to actuate lock slide override arm 424 from the position shown in Figure 9 to the position shown in Figure 11.
  • lock slide override arm 424 is pivoted into contact with locking slide 422 to move locking slide 422 from the second position to the first position where it is disengaged from retractable bolt 114 and no longer provides a physical barrier which prevents movement of retractable bolt 114 from the extended position to the retracted position.
  • motor slide 602 On movement of locking slide 422 from its second position to its first position, motor slide 602 is pushed against spring bias of helical compression spring 604 which compresses helical compression spring 604 and moves motor slide 602 from its active position to its inactive position where it is withdrawn within the body of motor module 418.
  • Figure 12 follows from Figure 11 and shows that a user is able to actuate spindle cam 406 via handles 106 or 110 to move the door into the open position whilst the override is active. That is, while a user is applying a push force to lock slide override arm 424 via the push-type key actuator via pin 122. Removal of the override, e.g. by withdrawing a key from a push-type key actuator results in lock slide override arm 424 being pivoted back to its disengaged position (as illustrated in Figure 17) due to helical compression spring 604 within motor module 418.
  • Push-type key actuator 1300 includes a housing 1302 with internal passage 1304; a key driven slide 1306 configured to be slidably retained within internal passage 1304 and having an exterior facing end 1308 with keyhole 1310, an interior facing end 1312, first detent recess 1314, and second detent recess 1316; a pin-tumbler assembly 1318; a spring-loaded ball 1320 and an engagement member in the form of an override pin assembly 1322 having a shaft 1324, a sheath 1326 which is located in slidable relationship with shaft 1324 via spring 1328 and locking bar 1330.
  • key driven slide 1306 When assembled, key driven slide 1306 is inserted into passage 1304 of casing 1302 in slidable relationship therewith, spring-loaded ball detent 1320 engages with first detent recess 1314 when push-type key actuator 1300 is in its neutral position.
  • This detent arrangement holds key driven slide 1306 in place during key insertion through keyhole 1310 and prevents key driven slide 1306 from being pushed into pins of pin-tumbler assembly 1318 causing lock binding.
  • the key tip contacts the spring-loaded ball 1320 and on continued insertion, pushes spring-loaded ball 1320 out of contact with first detent recess 1314 freeing key driven slide 1306 and permitting key driven slide 1306 to slide within passage 1304 on application of a pushing force.
  • spring-loaded ball 1320 and first detent recess 1314 interact to prevent sliding of key driven slide 1306 within passage 1304 during key insertion.
  • spring-loaded ball 1320 Once spring-loaded ball 1320 has cleared first detent recess 1310, application of sufficient pushing force causes key driven 1304 to inwardly slide within passage 1304 from its neutral position to its override position.
  • pin assembly 1322 In the override position, pin assembly 1322 is pressed into engagement with an override mechanism in a lock assembly, such as lock cartridge 112 (in which case, override pin 1322 is equivalent to override pin 122 of Figures 1 to 12).
  • override pin 1322 Whilst the override pin may be in the form of a simple shaft, the inventors have devised override pin 1322 with adaptable pin length for use with doors of different thicknesses. This is achieved, in this embodiment, by having a shaft 1324 and sheath 1326 arrangement with sheath 1326 being slidably mounted over shaft 1324 via spring 1328 and locking bar 1330.
  • spring 1328 is fitted within a recess of sheath 1326 and is held within the recess between a top surface of shaft 1324 and an internal ceiling of sheath 1326.
  • Locking bar 1330 is passed through windows 1332 of sheath 1326 and passage 1334 of shaft 1324 to mount sheath 1326 to shaft 1324.
  • Slidable movement of sheath 1326 over shaft 1324 is delimited by the height of windows 1332, such that sheath 1326 and shaft 1324 have a close together arrangement corresponding to a short pin length and a spaced apart arrangement corresponding to a long pin length.
  • Spring 1328 biases sheath 1326 from shaft 1324 into the spaced apart arrangement such that override pin 1322 has a long pin length.
  • Figure 14 and Figure 15 illustrate push-type key actuator 1300 in the neutral position with the override pin assembly having a long pin length (see Figure 14) when installed in a thick door and a short pin length (see Figure 15) when installed in a thin door.
  • Figure 14 illustrates that the sheath 1326 and shaft 1324 are biased apart by spring 1328 into the expanded state.
  • Pin 1330 is located at the bottom of window 1332 which delimits the expanded state.
  • Figure 15 illustrates that the sheath 1326 and shaft 1324 are pushed together against the bias of spring 1328 into the contracted state.
  • Pin 1330 is located at the top of window 1332 which delimits the contracted state.
  • Figure 16 is intended to contrast with Figure 14 and illustrates push-type key actuator 1300 in the override position with a key inserted in keyhole 1310 and with key driven slide 1306 being pushed inward such that interior facing end 1312 of key driven slide 1306 is moved distally from casing 1302 to actuate an override mechanism (see for example position of pin 122 in Figures 6 to 12).
  • Figure 17 is a front plan view of push-type key actuator 1300 with keyhole 1310 showing that the push-type key actuator 1300 has a slim line design with a width of only 8.5 mm. This contrasts with standard rotational pinned key cylinders used on entrance doors which typically have thicknesses of at least 16 mm.
  • FIG 18 is a partial perspective view of an escutcheon 1800 (such as escutcheon 108 in Figures 1 to 12) with push-type key actuator 1300 mounted therein.
  • Escutcheon 1800 has spring-loaded ball 1802 for engagement with second detent recess 1316 on key driven slide 1306 when push-type key actuator 1300 is in the override position.
  • This detent arrangement holds key driven slide 1306 in place and thus retains push-type key actuator 1300 in the override position so that a user can then actuate handle 106 or 110 to open the door.
  • key driven slide 1306 is pulled out of engagement with spring-loaded ball 1802 and the push-type key actuator 1300 is returned to the neutral position at which point the key is removed.
  • Disengaging push-type key actuator 1300 causes the manual override of an associated lock assembly to be removed, with the internal locking mechanism of that lock assembly automatically reengaging with the bolt (as described in relation to the embodiment illustrated in Figures 1 to 12) or automatically disengaging the lever from being able to retract the bolt (as will be described in relation to Figures 23 to 31).
  • FIG 19 is an exploded perspective view of a push-type key actuator 1900 according to another embodiment of the invention.

In this way, rotation of second clutching member 2416 (such as on rotation of handle 2310 when the first clutching member 2414 and the second clutching member 2416 are operatively connected) causes rotation of spindle 2314 and thus retraction of bolt 2316.

In this way, when first clutching member 2414 and second clutching member 2416 are operatively connected, rotation of handle 2310 causes rotation of clutching mechanism 2406 in its entirety, and thus retraction of bolt 2316. However, when first clutching member 2414 and second clutching member 2416 are operatively disconnected, rotation of handle 2310 only causes rotation of first clutching member 2414. First clutching member 2414 rotates about second clutching member 2416 while second clutching member 2416 remains stationary and therefore spindle 2314 and bolt 2316 remain stationary.
  • Clutching mechanism 2406 also comprises an engagement mechanism to operatively connect first clutching member 2414 with second clutching member 2416 in the form of pin 2408.
  • pin 2408 is seated within a recess 2422 of first clutching member 2414.
  • Pin 2408 has a first end which projects outward through an opening in recess 2422 of first clutching member 2414 for contact with slide 2400.
  • Pin 2408 is retained in recess 2422 via a flange.
  • Second clutching member 2416 includes recess 2426 for receiving a second end of pin 2408 therein. Pin 2408 is movable between a disengaged position and an engaged position.
  • first end of pin 2408 extends through the opening in first clutching member 2414 and the second end of pin 2408 is held within the first clutching member.
  • first end of pin 2408 is pushed at least partially inward with respect to first clutching member 2414 which causes second end of pin 2408 to project, at least partially, within recess 2426 of second clutching member 2416.
  • first clutching member 2414 and second clutching member 2416 are operatively connected via pin 2408. That is, rotational movement of first clutching member 2414 is transferred to second clutching member 2416 via pin 2408.
  • Pin 2408 also includes spring 2428 (see Figure 26) which spring biases pin 2408 to the disengaged position.
  • slide 2400 is moved to its second position (such as via motor 2410 or user actuation of push-type key actuator 2404) where slide 2400 pushes pin 2408 inward within first clutching member 2414 such that second end of pin 2408 projects within recess 2426 of second clutching member 2416.
  • Handle 2310 can then be actuated to retract bolt 2316.
  • Figure 26 illustrates the lock components of the escutcheon in a door closed position and in which the lock components have been locked via electric motor module 2410.
  • bolt 2316 is extended and engaged with a corresponding strike plate.
  • Locking slide 2400 is in the lock position with clutching mechanism 2406 being disengaged since pin 2408 is in its disengaged position. Rotation of handle 2310 is possible. However, handle 2310 is not operable to retract bolt 2316.
  • Electric motor module 2410 is internally sprung to bias locking slide 2400 to the locked position when motor module 2410 drives locking slide 2400 to the locked position.
  • Figure 27 illustrates the lock components of the escutcheon in a door closed position and in which the lock components have been locked via electric motor.
  • Figure 27 is similar to Figure 26, except handle 2310 has been rotated.
  • clutching mechanism 2406 is disengaged, and as such, spindle 2314 is operatively disengaged from handle 2310 such that rotation of handle 2310 does not cause rotation of spindle 2314 and retraction of bolt 2316.
  • Releasing handle 2310 returns the components to the position of Figure 26.
  • Figure 28 illustrates the lock components of the escutcheon in a door closed position and in which the lock components have been unlocked via electric motor. This arrangement differs from Figure 27 in that slide 2400 has been moved linearly upward to push pin 2408 to the engaged position such that the clutching mechanism between handle 2310 and spindle 2314 is engaged.
  • Figure 29 illustrates the lock components of the escutcheon in a door open position and in which the lock components have been unlocked via electric motor.
  • Figure 29 is similar to Figure 28, except handle 2310 has been rotated.
  • clutching mechanism 2406 is engaged, and as such, spindle 2314 is operatively engaged with handle 2310 such that rotation of handle 2310 causes rotation of spindle 2314 and retraction of bolt 2316.
  • Releasing handle 2310 returns the components to the position of Figure 28.
  • Figure 30 illustrates the lock components of the escutcheon in a door closed position and in which the lock components have been unlocked via push-type key actuator 2404. That is, starting from the arrangement of Figure 26, a correctly coded key 2900 has been inserted into push-type key actuator 2404, with push-type key actuator 2404 then being pushed within the body of exterior escutcheon 2308.
  • Releasing handle 2310 returns the components to the position of Figure 30. Ceasing the pushing force, such as on removal of the key, causes the lock to revert to the locked position illustrated in Figure 26.
  • locking slide 2400 is pushed downwards into its locked position due to a spring bias applied to locking slide 2400 via a spring located internally within electric motor module 2410, and pin 2408 is pushed downwards via spring 2428.
